The stainless steel bottle was custom-made for us by our friends at Fifty/Fifty, and of course it comes with a Rumble Go filter. Our early fans might remember this bottle's smaller cousin from our Kickstarter campaign in 2018. That bottle ended up getting such high marks that we decided it was time to bring it back, but this time in the larger 34oz form!

Rumble Go builds on the legacy of the original Rumble Jar by adapting the same award-winning filter so it can fit into more portable containers. Rumble Jar is built for your home. Rumble Go is built for the road.

Now it's simple to make professional-grade cold brew coffee anywhere you go. Just take some coarsely-ground coffee beans, add some lukewarm water, and give it a quick "rumble". Total prep time takes less than a minute, and by the morning you'll have delicious cold brew coffee. Watch how fast a batch gets brewed

Stainless steel insulated wide-mouth bottle (34oz). This highly durable bottle is built out of 18/8 stainless steel (the same kind of steel we use in our filters). Its powder-coated exterior is soft to the touch, and it also features a flip lid that's surpringly leak-proof. You can read more about the bottle here: Fifty/Fifty 34oz bottle  

Stainless steel filter. Built out of dent-resistant 18/8 stainless steel, this surprisingly sturdy filter will have you saying goodbye to those flimsy mesh filters, plastic parts, or disposable paper filters. All that stuff was designed for making hot coffee anyway. Experts agree that coarsely-ground coffee beans make the best cold brew, and 200 microns is the ideal hole size for perfectly filtering coarse grounds. Any bigger and you'll get too much sediment. Any smaller and you're drinking weak-tasting coffee. 200 microns is "just right". Our filter also features three notches on the side, which are there to help guide you in brewing so there's no need to precisely measure your grounds. see it up close

Universal, extendable base and cap. Designed using BPA-free, FDA-approved food grade silicone, the base features 11 different height adjustments that extend the filter by up to 1.5" so it can fit into a wide range of popular 16-32oz wide-mouth bottles. The base and the cap work together to keep the grounds secured inside the filter while also acting as shock-absorbers to prevent rattling. The cap's design allows the filter to nest fully inside your bottle, so it won't interfere with your bottle's airtight, leakproof seal. see it up close
